Since I setup the new version of this blog using Hugo, hosted on Cloudfront, I put together a Grafana instance to monitor traffic hitting the CDN. I noticed quite a number of errors and realised these would be dead links out in the wild. I wondered if I might figure a way of replicating the path structure I had with WordPress over here on Hugo. Initially I looked at the behaviours on the CloudFront distribution and figured quite quickly that it needed to be a Lambda@Edge.
